Trivia / The Happiest Millionaire

• Cut Song: The song "It Won't Be Long 'Til Christmas" was removed when the film opened at Radio City Music Hall, though it's since been restored.
• Died During Production: This was the last live-action film that Walt Disney personally oversaw, with him allegedly having viewed a first rough cut shortly before his death in December 1966.
• Recursive Adaptation: A movie, based on a stage play, based on a book, based on real world events.
• Re-Cut: The film originally premiered in Los Angeles as a Roadshow Theatrical Release clocking in at 164 minutes. To secure a Christmastime booking at Radio City Music Hall, over 20 minutes (including the song "It Won't Be Long 'Til Christmas") were cut; for the "general" release, the film was cut further to just under two hours. The 144-minute (Music Hall) cut was released on video in 1983, but the complete "roadshow" cut was restored and shown on The Disney Channel the following year.
